I tested next-20180219 and camera does not work there. It leads to nasty oops. I tried to capture the oops with dmesg > file, and that one oopsed, too. usb networking also has problems... fun. Camera works ok in V4.16-rc1, but if I use the camera, next shutdown will oops. I'll try to collect more data there, too.
